Be it known that 1, WILLIAM YoUL'rEN, a

subject of the King of England, residing an me No. 694,904.

- vertical tube carrying the mirror or 159 Victoria street, Westminster,in the county of London, En land, have invented certain new and usefulmprovements in In struments for Sighting Guns from Cover; and

According to my resent invention dispense with or great y reduce inlength the nsm coming in frontof the gunners eye, an I so arrangethe-mirrors or prisms that the first of the series me come, as with theprevious in strument, be ml or in place of the back sight of the rifleor other gun, while the last of the series of mirrors or prisms is soplaced that the emergent rays are deflected downward to is suitableposgon vfor entering the gunners some cases the instrument may consisttelly be d the back sight, cerryin one rism or reflector (comingimmediate be- 'nd such sight) from which the fieldo view is reflected bysuitable mirrors or prisms to the other end of the tube, where the lastmirror or prism is so placed that it deflects the said View downward ina slanting direction to the eye of the er.

I attach to the rifle a. bar or stem which may be adjustable and capableof revolution round about a pivot, so that it can be turned down out ofthe way when not in use. When in use, the said stem or bar is turnedupward and fixed approximately at right angles to the barrel, and u onthe said stem or bar, which may be gm noted to denote elevations, thesaid horizontal tube or reflectin instrument slides and may be set toanv e evetion required. The stem or bar may be suitably bent or curvedto cause the reflecting instrument to tilt over as it rises in order tokeep the said instrument in the proper position disc,

with respect to the line of elm, and in order that this inventionmey'be'better understood I will now proceed to describe the some withreference to the drewings accompenyin this specification, which show oneform 0 my improved hyposcope as applied to a. rifle.

figure 1 is a side elevation of a. portion of a rifle with my improvedby oscope attached thereto. Fig. 2 IS a plan of seme. Fig. 3 is a frontelevation of the hyposcope detached from the rifle.

The same letters of reference are employed to denote the same arts inall the views.

oshows the mem horizontal tube of the.

hyposcope provided with prisms at b and 0. These prisms are mountedinsuch a we. that can be slid into and out of sec end the ,of the tube a,so that when the instrument is not in use they can be turned in such aw'ey that the risms are protected by the tube a.

bracket-piece attached to the horinontal tube a and provided with a slotat e.

f is a screw rovided with a. milled head 9 by means of which the screwfineiy be turned end made to project into the slot 5 to fix the"hyposoope at enyreqsired" esition on the stern h. At the'other'endo thetubes, and opposite the prism c is placed a short cham her or tube 1,,provided with two reflectingsurfaces or n and o p. In the instrumentshown in the drawings the reflecting-surfaces are formed by means of aprismatic piece of the shape shown in the drawings and bound ed in Fig.1 by lines m 11,11, 0, 0 p, and p m.

Referring to the stem h, this is provided in the form shown at Fig. 1with an extension g and with slots 1 r.

s is a. screw-pin passing through the slot 1 and provided with e milledhead'ii u, 'v, and w erepins which may be fastened on the rifle or, asin the case of the instrument shown on the drawin s, the wholeerrengement can be remov from the rifle, being mounted on a handuerd 2:,which clips over the rifle and can e immediately placed in position orremoved.

The stem, which is shown in full lines raised at Fig. 1, me be loweredinto the position shown dotte when the h poscope is removed by looseningthe milled eed t, sliding the stem upward on, the screw-pin 8, turningthe stem it down parallel to the rifle, edjusting. it so as to en agewith the pin it, and tightening the milled end 15.

' pressed it is kept in t It will be observed that the stem h in theWhat I claim, and desire to secure by Letform shown in the drawings isnot straight, ters Patent of the United States of America, but curvedslightly, the object of this being isthat as the hyposeo e is raised anddel 1. .In an apparatus of the character de- 5 be proper position forscribed, the combination with a rifle, of a sighting.Suitablegraduationsindicatingthe curved graduated sightingarm connectedranges are marked on the stem 71. l thereto, of a horizontally disposedtube I do not wish to confine myself to the par- I mounted to slidevertically upon said sightticular form of instrument shown 011 the fing-arm, means for rlamping said tube at the 40 drawings andhereindeseribed, as the partieul desired position, prisms carried bysaid tube, lar form of the hyposcope may be varied, and means forreflecting the light emerging while retainin the principle of anadditional from the last of said prisms at an inclination c reflectingsurface or surfaces so placed as to downward, substantially asdescribed. reflect the image of the object aimed at diag- 2.
